PP (Polypropylene) – Frequently Asked Questions
Q1: What PP grades does CISKO offer?
We supply Hanwha TotalEnergies PP compounds in three main series: TB series (mineral filled – high stiffness and dimensional stability), GH series (glass fiber reinforced – high strength and heat resistance), and FH/FB series (flame retardant – UL94 V-0/V-2 certified).
Q2: What are the typical applications for mineral filled PP?
TB series is ideal for automotive E&E parts, washing machine interior components, detergent boxes, and household goods requiring excellent heat resistance, dimensional stability, and high impact strength.
Q3: What are the benefits of glass fiber reinforced PP?
GH series offers excellent physical properties, high heat resistance (HDT up to 163°C), low shrinkage, and superior processability. It is widely used in automotive E&E parts, household goods, and industrial components.
Q4: Which flame retardant PP grades are available?
We offer FH44 (UL94 V-0, non-dioxin, harmless to humans and environment) and FB51 (UL94 V-2, high impact). Both are suitable for automotive E&E parts, motor cases, and appliance housings.
Q5: Does CISKO provide technical documentation?
Yes. Every PP grade comes with TDS (Technical Data Sheet), SDS (Safety Data Sheet), and COA/COC (Certificate of Analysis/Conformance). REACH, RoHS, and UL documentation are also available upon request.
PEI (Polyetherimide) – Frequently Asked Questions
Q1: What PEI brands does CISKO supply?
We supply SABIC Ultem™ PEI (full range: 1000, 1010, 1285, 2100-2400, 3452, 4000, 4001, 4002, 4211) and Valiant PEI (domestic, cost-effective: VAT002, VAT002HF, VAT002G10/G20/G30, and micron powders P50-P350).
Q2: What are the key properties of PEI?
PEI offers high heat resistance (Tg 217°C, RTI 170°C), high strength and stiffness, inherent flame retardancy (UL94 V-0 at 0.25-0.75 mm), excellent electrical insulation, and good chemical resistance.
Q3: What are the main applications of PEI?
PEI is used in aerospace interior components (FAR 25.853), 5G antenna and RF components, medical devices (FDA grade available), automotive E&E parts, semiconductor equipment, and industrial connectors.
Q4: What is the difference between Ultem PEI and Valiant PEI?
Ultem PEI (SABIC) is the global industry standard with broad regulatory approvals. Valiant PEI is a domestically produced, cost-effective alternative offering equivalent performance, with the same Tg (217°C), UL94 V-0 rating, and mechanical properties – ideal for customers seeking value without compromising quality.
Q5: Does CISKO provide PEI powders?
Yes. We stock Valiant PEI micron powders: VAT002P50 (D50 50µm), VAT002P100 (D50 100µm), VAT002P200 (D90 200µm), and VAT002P350 (D90 350µm) – suitable for SLS 3D printing, compression molding, rotational molding, and ceramic binder applications.
